Hi,
I would like to chime in one more time about the SQ of TIDAL.
I still have, but will soon drop, my subscription to Spotify Premium and keep TIDAL. Why? Because after having TIDAL for some time now, I queued up the album by "OMI Me 4U", both on Spotify and TIDAL and performed an A/B, Tidal crushed Spotify hands down in terms of SQ! I can only guess for members that do not notice a substantial improvement with TIDAL vs Spotify, that there may be something amiss in their systems? I really don't know.
For me, and "MY" ears, TIDAL has proven to me that this is the streaming App to keep. For those that do not hear any substantial difference, stick with the less costly Spotify Premium.
Hey, life is good, no worries!
